Definitions

  • the present invention relates to the use of a silicon containing compound as drying agent for polyolefin compositions.
  • Polyolefin compositions often comprise several polymeric components, as for example polyolefin resins with different properties, such as different molecular weights, or different content of comonomer. Furthermore, organic and/or inorganic additives such as stabilizers are usually present in a polyolefin composition. The nature and amount of these polyolefin resins and these additives is dependent on the particular use a polyolefin composition is designed for.
  • Each of the different components a polyolefin composition is made of may comprise small amounts of water.
  • the different components come together and the final composition is formed. Also the amounts of water present in the several components are added in the step of compounding.
